Director Alfonso Cuaron's Gravity stars Sandra Bullock as Dr. Ryan Stone, a scientist on a space shuttle mission headed by astronaut Matt Kowalsky (George Clooney), a talkative, charismatic leader full of colorful stories that he shares with his crewmates as well as mission control. As the two are on a space walk, debris hits the area where they are working, and soon the pair finds themselves detached from their ship and stranded in space. While figuring out what steps they can take to save themselves, Stone grapples with a painful past that makes her consider giving up altogether. Gravity screened at the 2013 Toronto International Film Festival.
